Scanning Microscopy

The emerging importance and pervasiveness of scanning probe microscopy has prompted the Institute to develop a new, dedicated laboratory. (Previously, our AFM was operated within the electron-optics laboratory.) We currently have 3 scanning probe microscopes: a NanoScope IIIa Multimode SPM, a NanoScope II Contact mode SPM and a Thermomicroscopes Explorer SPM. A wide-range of users from Engineering and Science work in the facility typically making use of the NanoScope III instrument. The other two microscopes are used for longer-term dedicated experiments in polymer physics and nano-lithography (Chemistry). The NanoScope II will be equipped as an electrochemical STM and AFM to etch and deposit features on semiconductors and related surfaces. This will allow the creation of nanoscale surface sensors and other structures.
